Tips
To deepen Riley's understanding of diffusion and osmosis, engage in hands-on experiments such as observing osmosis with potatoes in different salt solutions or constructing models of cell membranes. Encourage Riley to create a short video or infographic summarizing these concepts to reinforce learning visually and verbally. Exploring related cellular processes like active transport can broaden their comprehension of membrane dynamics. Additionally, discussing the real-life implications in human health and environment will help Riley connect science to everyday life, making the abstract concepts more tangible.
